Astrocytes Optimize the Synaptic Transmission of Information
Figure 6
Synaptic transmission (not normalized here, but at a fixed presynaptic spiking frequency of 5 Hz) versus astrocytic feedback.
The baseline transmission probability is fixed P≈0.18, while the number of active zones varies. The vertical line denotes the value of α that yields the experimentally measured transmission probability of the tripartite synapse.
